I don't like it as a hold and I don't like its effect on the market. A lot of the down markets have been caused by the double shelters USDT causes (hide from alts to bitcoin when bitcoin goes down, but hide in tether when bitcoin is dropping..) It just all plays in hand with the bart candles moving low volume markets with shorting on margin, people stacking futures for price going lower, etc. I think the only shelter for BTC should be USD or fiat currencies on approved exchanges.. not sheltering with this perceived 1.00 value worth alt coin.. would make the market a LOT more stable if this wasn't incorporated so heavily into how people abuse it as a shelter.
